Didn't see anyone post the steps to get to the 2210.
You might be able to eliminate it or at least reduce the penalty. You can go to Federal Taxes tab or Personal tab, under Other Tax Situations and select Start by the Underpayment Penalties. You will answer a series of questions that may reduce or eliminate the penalty. Or you can elect to have the IRS figure the penalty for you. It's form 2210. And it is just an ESTIMATED penalty. It's common and normal and expected for the IRS or state to bill you for more or send you a refund.
